Unique Blueair HEPASilent Technology
The new Classic 405 uses Blueair's patented HEPASilent Technology to remove virtually all airborne pollutants in medium size rooms up to 40m2. Using the best in electrostatic and mechanical filtration, the HEPASilent Technology is a revolutionary combination of advanced filter media and an encapsulated particle-charging chamber. This ensures that your Blueair purifier delivers results far superior than either mechanical or electrostatic technology alone.

Removes more of the most harmful pollutants than standard Hepa filters.
Theuniquedesign enables all Blueair purifiers to achieve 99.97% filtration efficiency, all the way down to .01 micron. Most Hepa filters only trap particles down to 0.3 micron. The smaller particles trapped by the Blueair technology mean that your room will be continually protected from much more of the most hazardous smaller particles like viruses and bacteria than it would be with basic hepa filtration.

In touch with your clean air.
Touch sensitive easy-to-read LED icons let you see the status of your air purifier’s Wi-Fi connection, operating speed and filter status. Adjusting operation is simple, Just touch. Downloading the free Blueair Friend app will also enable you to control the new Classic via WiFi from afar using any smart device. (Don't worry if you are not interested in the WiFi functionality, the 405 can also be fully controlled using only the LED Icons on the top of the machine!)

Want to see even more detailed information on your indoor air quality?
Linking your Classic 405 to the optional Blueair Aware monitor via Wifi will also enable you to see detailed information about your actual indoor air quality on your smart device app and access outdoor air quality data in real time in most major urban areas too. Alternatively, consider the Classic 480i model which has this feature and air quality sensors already built-in as standard.

Quiet Performance.
A perfect choice for medium to large rooms, the Classic 405 packs quite a punch, cleaning the air in rooms up to 40m2 up to five times an hour ( that's one complete air change every twelve minutes). The unit is also extremely quiet in operation.

The design is not only attractive but also built to last. Each machine is finely crafted from galvanized steel and is powder coated for durability and environmental protection that produces no chemical off gassing.

AHAM certified room size is the size of room in which the air purifier can provide a full five air changes per hour. Therefore refreshing all of the air in the room through its filters once every twelve minutes.This is more relevant than 'maximum' room size which does not reflect an air purifiers genuine effective capability. Always be sure to only use the 'AHAM certified' room size for true comparison purposes.

CADR stands for Clean Air Delivery Rate and is an actual measurement of the amount of filtered air provided by the machine.This is the only true way to compare like for like between air purifiers when assessing how powerful they are. CADR is not the same as air volume which will always appear higher due to the fact that it is only a measurement of the units fan power (with no filter Installed).

***Carbon Filters
Carbon filters remove chemical fumes including VOC's, traffic combustion gases, pet odours, tobacco smoke and many more gaseous pollutants.However not all carbon filters are the same. Basic carbon 'sheet' filters are generally lightweight and have little capacity to adsorb these pollutants effectively. On the other hand filters containing actual carbon 'granules' are infinitely more effective and should always be chosen over carbon sheets where the most effective gaseous pollutant removal is required.

We've never owned an air purifier before and were thinking about getting one for our open plan living/dining room (approx. 35 sq m / 376 sq ft). Our research quickly led us to the Blueair brand. We specifically wanted something quiet, energy efficient and powerful. The 405 ticks all these boxes and more! My better half and I both suffer from really bad hayfever and I also have asthma... and since owning the 405 - we both show little to no hayfever symptoms. I've also noticed I'm actually using my inhalers less now (we've only had the unit a little over 1 week!). Our living area - in fact the whole ground floor including our kitchen and hallway (where the kitty litter is located) no longer smells stale and stuffy - it's like a window has been permanently opened! The unit is very quiet, so much so we've left it on the middle setting and hardly notice it. After reading several negative reviews about the app... I was worried it would be a nightmare to pair - but it was in fact very easy and has worked flawlessly as a remote (not much else you can do other than set up a night time schedule or lock the control panel on the device). The Blueair Classic 405 is an amazing bit of kit (the performance test results speak for themselves) and comes with a 5 year warranty meaning Blueair clearly stand by their products! To me it's a no brainer!

Only had for just over a week. So far so good - Good looking, well built and most importantly does the job. Basic but "does what it says on the tin." Excellent service from Breathing Space. Will buy a smaller one for small bedroom.
